Red River Jasper is also called Lightening Jasper with it's streaks of red, tan, grey and black. Names of stones are often confusing. It seems that this Red River Jasper comes from South Africa and not the same Red River Jasper that comes from China (also called Cherry Creek Jasper). You can see that these cabs look total different than the Cherry Creek stones. I'm figuring that there are several Red Rivers in the world that are named as such.
There may be reflections on the cabochon from the studio lights.
